The invention discloses a cogeneration system based on the supercritical carbon dioxide brayton cycle. The cogeneration system based on the supercritical carbon dioxide brayton cycle comprises a fuel combustion unit, a supercritical carbon dioxide brayton power generation unit, a user heat supply unit and an industrial gas supply unit. The fuel combustion unit (1) is used for generating high-temperature smoke to provide heat for the supercritical carbon dioxide brayton power generation unit. After supercritical carbon dioxide brayton power generation unit absorbs the heat provided by the fuel combustion unit, does work and generates power, the waste heat is used for heating the user heat supply unit and the industrial gas supply unit. The user heat supply unit is used for absorbing the waste heat of the supercritical carbon dioxide brayton power generation unit and supplying heat to residents and the industrial gas supply unit. By the adoption of the cogeneration system based on the supercritical carbon dioxide brayton cycle, on the basis of supercritical carbon dioxide cycle power generation, the smoke and the carbon dioxide are utilized to conduct heat exchange, and therefore the efficiency of a unit is improved.
Description
Technical field: [0001] The present invention relates to a kind of based on supercritical CO 2 Brayton cycle combined heat and power system, which belongs to supercritical CO 2 field of power generation technology. Background technique: [0002] my country's current power generation system is mainly based on thermal power generation, of which coal resources account for about 60% to 70% of China's power generation, occupying an extremely important position in my country's power generation industry. Therefore, it is particularly important to improve energy heat conversion rate and overall power generation efficiency. [0003] Thermal power plants using coal resources use the Rankine cycle as the basis for power generation, and use water vapor as the energy transfer medium to realize energy conversion and provide and transmit electricity. On the basis of existing technology, from subcritical units to supercritical and ultra-supercritical units, the installed capacity has als...
